Endoscopic pneumatic balloon dilatation for achalasia of the cardia.

This study evaluated the efficacy and safety of endoscopic pneumatic balloon dilatation as the initial treatment for achalasia of the cardia. 15 patients with achalasia underwent a total of 19 dilatations using the new polyethylene dilator (Microvasive Rigiflex Balloon Dilator) over the last 6 years. An overall treatment success rate of 93% was achieved. 11 patients (73.3%) have not required a further dilatation and 3 patients (20%) required between 1 and 2 further dilatations. Elective surgery was necessary in 1 patient. The mean follow-up period was 31.5 months. There was no complication or death attributable to the procedure. Endoscopic pneumatic balloon dilation is a safe and effective treatment for achalasia and should be considered as the initial treatment of choice in most patients with achalasia.
